Mastering the Integrated Workstation Ledge

The standout feature of this Kore series sink is its integrated workstation ledge, which functions much like a modular workbench in a professional kitchen. Just as a carpenter uses a dedicated track to slide tools across a worktable effortlessly, this built-in tier allows you to slide the custom bamboo cutting board smoothly across the top of the sink. By elevating your prep work directly above the 12-inch by 11-inch inner bowl, you create an efficient vertical workflow that keeps food scraps sliding straight into the drain and off your valuable countertops.

Installation Guide

  • Verify that your minimum cabinet size is at least 18 inches and that your countertop cutout matches the 15-inch by 15-inch outer dimensions before dropping the unit in.
  • Apply a bead of silicone sealant around the underside of the extra-thick beveled mounting deck to ensure a secure, watertight top-mount seal against the countertop.
  • Secure the sink using the included mounting hardware, tightening evenly around the perimeter for a flush, stable fit.
  • Attach the rear-center drain assembly and matching cover, connecting your plumbing to take advantage of the extra storage space created underneath.

Care & Maintenance

  • Daily Rinsing Rinse the stainless steel basin thoroughly after each use and wipe it dry with a soft cloth to prevent water spot accumulation.
  • Gentle Cleaning Use a mild dish soap and a non-abrasive sponge or microfiber cloth to clean the wear-resistant surface during regular maintenance.
  • Avoid Harsh Chemicals Do not use steel wool, wire brushes, or harsh abrasive chemical cleaners, as these can scratch and dull the stainless steel finish.
  • Prevent Rust Spots Avoid leaving wet iron or cast-iron cookware sitting directly on the sink surface for extended periods to prevent surface discoloration.
  • Accessory Care Hand wash the included bamboo cutting board periodically and treat it with food-grade mineral oil to preserve its natural grain.

Engineering Excellence for Compact Spaces

Choosing a high-performance sink for a secondary prep area or entertainment space requires balancing physical footprint with uncompromised utility. The Kraus Kore Series utilizes heavy-duty TRU16 stainless steel, a robust 16-gauge material that provides superior structural integrity compared to standard thinner sinks. This extra thickness protects against heavy cookware impacts and daily wear, ensuring that your bar or galley sink maintains its structural soundness and polished appearance over years of frequent use. Brand trust is built upon this level of meticulous engineering, where every detail from the rear-set drain placement to the thick sound-dampening pads works in harmony to elevate your daily routine.

Beyond immediate convenience, investing in a well-designed single bowl workstation sink contributes to a cleaner, more hygienic food preparation environment. By integrating a custom bamboo cutting board directly over the basin, crumbs and liquids are managed in one designated zone, protecting your surrounding countertops from moisture damage and staining. The smooth, rounded corners inside the zero radius style bowl prevent food buildup over time, making routine maintenance quick and effortless. This thoughtful combination of smart spatial design, resilient materials, and user-focused accessories delivers lasting value for any compact kitchen or entertaining space.

Why This Is the Right Choice

  • Lasting Durability Constructed from heavy-duty 16-gauge stainless steel to withstand daily kitchen demands for years to come.
  • Quiet Performance Engineered with specialized NoiseDefend pads that dramatically lower sound and vibration during food prep.
  • Simple Top-Mount Setup Features a drop-in design with a pre-drilled faucet hole for straightforward installation on any countertop.
  • Space-Saving Workspace Maximizes counter utility in compact spaces by combining your prep board and sink basin into one footprint.
